In the framework of Network Function Virtualization (NFV), we address in this work the
performance analysis of virtualized network functions (VNFs), wherein the virtualization of …

In the framework of network function virtualization, we consider in this paper the execution of
Virtualized Network Functions (VNFs) in data centers whose computing capacities are …

Virtual Network Functions (VNFs) are often realized using virtual machines (VMs) because
they provide an isolated environment compatible with classical cloud computing …

We address in this paper the problem of modeling Virtual Network Functions (VNFs) in order
to devise execution principles. We specifically represent a VNF as a chain of sub-functions …

Network Function Virtualization promises to reduce the overall operational and capital
expenses experienced by the network operators. Running multiple network functions on top …

Network functions virtualization (NFV) promises to bring significant flexibility and cost
savings to networking. These improvements are predicated on being able to run many …

Network Function Virtualization (NFV) is an emerging network architecture that employs the
concept of virtualization and allows the consolidation of many network services on top of an …

Network Function Virtualization has dramatically increased the flexibility in the deployment
of network services, however the execution of virtual functions on compute nodes equipped …

Using Network Functions Virtualization (NFV), network functions are virtualized and chained
together to provide a network service. Often, a service chain can be allocated in multiple …

Today's networks provide more than connectivity. Network functions such as firewalls,
caches, WAN optimizers play a crucial role in improving security and performance …
